VEHICLE WHEEL-RIM.

T10-dll whom t may concern:

@mit known that I, EDWIN COUPLAND Straw, 'a citizen of the United States, lre

sidi at Akron in the county of Summit I ntatefof Oh and.y f io,- have invented certain new land. useful Improvements in Vehicle Wheelrims, (Case AL) of which the following is a specification.

This. invention relates to that class of vel This invention isa modification of the .form of rim shown and claimed broadly in my. application Serial No. 375,716, filed May 25, 19.07. In this modication ythe de- 'tachable' rim Avis split so that it may be contracted sufiiciently to permit the tire retaining flanges to pass over it, and it is provided with means `for positively expanding andcontracting the rim and holding it in its `different positions of adjustment. The detachable rim after being placed in position upon the fixed rim can be contracted by the lmeans just mentioned to clamp the fixed rim in firm and closeengagement.

I -have `chosen one specific form vof my invention for purposes of illustration, but itis not to be understood 'that I intend to limit myself to the precise structure illustrated, but that modiiications may be freely made so long as the essential and operative combination of elements is retained.

In the drawings forming a partof this specification," Figure 1 is` a side elevation of a portion of a wheel fitted with my rim showing the detachable rim in place upon the fixed rim and showing the adjusting means for the ends of the detachablemiin, the Valve stem, and' one of the set screws fwhich I mayuse as additional means for holding the detachable rim in place'. Fig. 2 is a cross section of the parts shown in Fig. 1 taken on line II-II of Fig. 1. Fig. 3 is a bottom plan view of the run shown in Fig. 1 showing the adjusting means, one of the wheel spokes being shown Specification of Letters Patent.

in section. Fig. 4 is as'iide elevation of a portion of the detachable rim and tire showing the ends of the detachable rim spread fapart to permit the detachable rim to be slipped over the lixed rim and in dotted lines showing the ends of the detachable rim lapped by each other to redce its diameter.

The same 'reference numerals are used to indicate the same or like ts throughout.

Referring to the drawings by reference numerals: 1 designates the wheel felly to which is rigidly attached, in any' suitable manner, the fixed rim 2; adapted to engage this fixed rim Ais the split detachable rim 3 having the upst-anding fian'ges 4: at its edges.A Inclined faces 5 and 6 are provided on the fixed and detachable rim' respectively, said faces being inclined slightly downward and inward so that when the detachable rim is drawn tight in its normal position upon the fixed rim there can be nopossibilityof relative movement. Adapt-edl to seat upon the detachable rim are the endless tire retaining flanges 7 which are held from outward' movement by theflanges 4. These tire retaining flanges are formed to engage the foot of the tire 8 which is shown as a clencher tire though it is obvious that any other form vof tire might .be used,the retainingl flanges being formed of corresponding shape. For the purpose of expanding and. contracting the detachable rim, each end of the rim is provided with a pair of lugs, one4 at each side of the end. On one end of the rim, lugs 9 provided with screw' threaded apertures are formed, and on the other end of the rim, yolreshaped lugs 10 are formed. Threaded bolts 11 provided with heads 12 are screwed into the lugs 9. The heads 12 are of suitablev form to bear againstthe yoke shaped lugs 10 and to be yengaged by a wrench or screw driver.

with the lugs 9 is depressed so that the bolts ll Will'disengage the yoke shaped lugs lil when the ends of' the detachable rim may be lapped past each other as shown in dotted lines in Fig. et. One of the tire flanges 7 is then slipped over the rim 3 which is easilyV made possible by the reduced diameter of the rim. The tire is then slipped over and engaged With the ange 7 and the other flange 7 is put on. The ends of the rim are then spread apart, bolts 1l slipped baclr into their slots in the lugs l() When, by unscrewing the bolts and screwing up .the nuts 13, the lugs9 and l() and the ends of the detachable rim are forced apart until the rim tightly engages'the inner faces of the flanges 7 as shown in Fig. 1l. The tire 8 can then be inflated and the detachable rim and tire are ready' to be immediately Iapplied to the Wheel or reserved for emergency. lVith the detachable rim expanded as shown in Fig. 4t its inner diameter is greater than the outer diameterl of the fixed rim so that in order to apply the detachable rim and tire it is only necessary to insert the valve stem in its proper opening in the fixed rim and telly and slip the detachable rim over the 4fixed rim into its seat. Then by unscrevving the nuts 13 and screwing up the bolts l1, the

ends of the detachable rim are drawn to-4 I gether, thus reducing the diameter of the detachable rim and the. inclined faces 5 and rim. Cams or other equivalents ofthe set.

screws may be used, 'but such additional locking device is not essential.

lt will thus be seen that arim has been provided in which the part engaging and holding the "ire can be quickly removed and another similar part carrying a ready in* flated tire put in its place and also one in. which the tire can be quickly and easily taken oft' from the detachable part of the for repairs. aving 'thus described my invention, I claim:

1. ln combination in a vehicle Wheel. a .fixed rim, an tip-standing flange on each side of said rim, the outer faces of said fianges comprising ,the surfaces of frustums of' cones Whose smaller bases 'face each other, and a detachable rim. mounted on said fixed rinn said detachable rim being provided -with conical faces enga gingv the outer faces of the flanges of said fixed rim, said conical faces constituting the only bearing surfaces of the detachable rim upon the fixed rim:

lin combination in a vehicle Wheel, a fixed rim, a split detachable rim7 a lug'carried by one end of said rim, a bolt carried by said lug, and a yoke shaped lug on the other end of said rim opening downwardly and adapted to removably engage said bolt.

3. ln combination in a vehicle Wheel, a fixed rim, a split detachable rim, tire engaging means carried by said split detachable rim, a pair of lugs each provided with a screw threaded aperture carried by one end of said rim, a pair of corresponding lugs each provided with an open bottom slot car ried by the other end of said rim7 screw threaded bolts adapted to engage the apertures in said first named lugs and provided with heads adapted to engage the outer faces of said second named lugs, and nut-s screwed on said bolts' and adapted to engage the inner faces of said second named lugs.

ft. ln combination in a vehicle Wheel, a fixed rim7 a split detachable rim7 endless tire engaging flanges mounted thereon, and means for contracting said split rim to cause it to clamp said fixed rim.
